Are winter tires needed with the "D"??

Little Known Fact: All Season Tires mean All Florida Seasons or for those of us up North All Seasons....Except for Winter. All Season tires are directly responsible for many accidents and that is why we don't even think of leaving them on once the temperature stays below 50 degrees consistently. All Season Tires are just too Dangerous for Iowa Winters. (Plus only winter tires can make it up our driveway in the winter time).

With the exception of "severe service" all season tires. I know of two: Nokian WR-g3 and Yokohama Y370 (don't know if this is Canada only or not). There may be others. I use the Nokians.
